Diagonals necessarily bisect opposite angles in a
rectangle(b) parallelogram (c)isosceles trapezium    (d)  square

DACRUISE 5.4State whether True or False.(a) All rectangles are squares(e) All kites are rhombuses.(b) All rhombuses are parallelograms(h. All rhombuses are kites.(c) All squares are rhombuses and also rectangles (9) All parallelograms are trapeziums.(d) All squares are not parallelograms. (h) All squares are trapeziums.

The diagonals do not necessarily bisect the interior angles at the vertices in a

The figure formed by joining the mid-point of the adjacent sides of a parallelogram is a rectangle (b) parallelogram (c) rhombus (d) square

The diagonls of a quadrilateral bisect each other. This quadrilateral is a rectangle (b) kite (c) trapezium (d) none of these

In a diagonal of a parallelogram bisects one of the angles of the parallelogram; it also bisects the second angle.

If diagonal of a parallelogram bisects one of the angles of the parallelogram,it also bisects the second angle.Also,prove that it is a rhombus.

If two diameters of a circle intersect each other at right angles,then quadrilateral formed by joining their end points is a rhombus (b) rectangle (c) parallelogram (d) square

The diagonals of a rectangle are equal and bisect each other

Say True or False : (a) Each angle of a rectangle is a right angle. (b) The opposite sides of a rectangle are equal in length. (c) The diagonals of a square are perpendicular to one another. (d) All the sides of a rhombus are of equal length. (e) All the sides of a parallelogram are of equal length. (f) The opposite sides of a trapezium are parallel.
